PatentedNov. so, 1915;.

hinged half molds on the carrier are provided each with a can bodyejector or arm which engages the can body when the hinged half moldopensand thus ejects the flanged can body froml the mold and delivers itinto the. discharge. chute asthe carrier rotates.

The side guides between which the flanging molds on the carrier pass areprovided with converging and adJustable centering gu des, preterablyof ayielding character, or coning tool spindles mounted on thecarrier, one

set at each end of the molds- The carrier is preferably composed of anumber/ofseparate heads secured together and rotating as a unit, and itis preferably supported and journaledon a central stationary ornonrotatable sh'aft fixed tothe frame.

My invention also consists in the. novel construction of parts anddevices and in the novel combinations of parts and devices herein shownand described and more particularly specified in'the claims.

One embodimentof my invention, and the preferred one, is illustrated inthe accompanying drawing forming a part of this specification.

In said drawing, Figure l is a side elevation of a can body flangingmachine embodying my invention. Fig. 2 is anend view. Fig. 3 is adetail, central, vertical section. Fig. l is a detail vertical sectionon line of Fig. Figs; 5, 6 and. 7 are d,e tailsectionson lines. 5 5, 6+6and1-77.of Fig; 4 respectively. Fig.8 is a detail perspective. viewshowing. one of. the Hanging molds of the carrier. Fig. 9 isa detail,section showing the side. guides for'centering the-can bodies and thecentering springsor devices, with which the. side guides, are,.pro,-.ided, and Fig; .10 is added section oi onef-I th flan ingamolds; andgothe. fiangin te ers eoact gther with,

' ll epnj msth immsei furnished with an arm 24 connected by a themachine, 12 a continuously rotating carrier, preferably supported :andjournaled upon a fixed or non rotating central shaft 13 supported insuitable brackets 14 on the frameof the machine. The carrier 12, forconvenience of construction, is preferably composed of a number ofseparate pieces or heads 15, 16, 17 and 18. The continuously rotatingcarrier 12 is furnished with a plurality of'fianging molds19, preferablysix in number each slightly less than the--can body in length andconforming thereto in diameter, and each havingwa segment or jaw 20adapted to open and close toreceive and clamp the can body in the mold.The inner or fixed segment-of the mold is preferably made integral withthe heads 15 and 16 of the carrier. The hinged or opening and closingsegment 20 of the mold is connected to the fixed segment by a hinge orpivot pin 21 and is opened and closed preferably by means of astationary cam 22 securedto the fixed shaft 13 and fitting in a chamber23 provided for itfin the carrier heads 15, 16.

Eachof the hinged half molds or jaws 20'is link 25 having a roller 26which travels in the stationary cam 22 as the carrier rotates. Each ofthe molds 19 has a registering shoulder or ledge 27 for the free edge 28of the hinged jaw 20 to shut against. Each member ofthe flanging mold isalso provided with an ejector or arm 29 fitting in the correspondingrecess 30 of the other member of the mold when the hinged jaw of themold is closed, and which engages the can body and operates toautomatically eject the flanged can body from each member of the moldwhen the hinged member 20 opens, as will be readily understood from Fig.8 of the drawing. The ejector arms or fingers 29 are preferablyinseparate pieces from the segments of the mold and secured thereto byscrews. Two are preferably attached to the fixed member 19. of each moldand two to the hinged member 20 thereof. The can bodies 31 which are tobe provided with flanges 32 at each end are automatically delivered oneby one to the flanging molds by a delivery chute 33 to which the canbodies are fed by an elevator 34 having fingers 35.

The feed chute 33 is preferably furnished witha curved spring holder 36for retaining the last can body in the delivery end of the chute 33until it is forced out of the chute into the open mold 19 on the carrier12 by the fingers acting upon adjacent can bodies in the chute 33. 7

After the hinged halfmolds or jaws 20 have been closed upon the can byoperation of the stationary cam 22 and the connecting links 25,the jaws20 are held firmly closed during the seaming operation by means of acurved guide or shoe 37 whichisengaged by rollers 38 journaled on arms39 of the jaws molds and adapted to reciprocate, and each also to berotated on its own axis. Each of these reciprocating and axiallyrotating flanging tool spindles is furnished with a spur gear46 whichmeshes with a central gear 47, the teeth of which are made wide enoughto admit of the necessary longitudinal movement of the spindle 45without disengaging its spur gear 46 from the central gear 47. Theflanging tool spindles 45 are automatically reciprocated as required,preferably by means of stationary cams 48 on the frame of the machine,which are engaged by yoke levers 49 carrying rollers 50 for engagementwith the cams and pivoted to lugs 51 on the head 18 of the carrier 12,and which yoke levers'have pins engaging grooved collars 52 fixed to thespindles 45, a coiled spring 53 serving to retract the Spindles 45. i 9Each of, the flanging tool spindles 45 has secured thereto a tool holderor crank arm 54 furnished with a screw stud 55 upon "which is journaleda flanging roller 56, the same being furnished with a curved face orshoulder 57 adapted to coiiperate with the end face or shoulder 58 ofthe flanging mold 19, 20 to turn or form the flange 32 on the can body31 as the flanging roller rotates on its own axis and is carried aroundthe interior of the flanging mold by'the' axially rotating flanging toolspindle 45.

The central gear 47, instead of being stationary orfixed to the centralshaft 13 is rotated in the opposite direction from the carrier 12 andisfurnishedwith a sleeve 59 surrounding the central shaft 13 carrying agear 60 which meshes with a gear 61 on the countershaft 62 which mesheswith a gear 63 on the shaft 64. The carrier 12 is furnished with a spurgear preferably in a separate piece from the head 18 and bolted thereto,and which meshes with a gear 66 on the shaft 64. The shaft 64 and thegears 60, 61', 63, 65 and 66'and countershaft 62 are duplicated at eachend of the ma-. chine and one of the shafts 64 is furnished with adriving pulley 67. 1

After the can bodies are flanged they are discharged from the flangingmolds into a discharge chute 68 which delivers them to the elevator orconveyer 69 for'the flanged can bodies.

In order to accurately center the can bodagrenaes end of the can :body,.I provide the 'side guides on the frame of the machine-and.

between which the Hanging molds pass as the carrier rotates withslightly converging and adjustable centering guides .71, the samefitting in slots 72 inthe side guides 70 and securedthereto at one endby screws .73 and fitting at their free ends against adjusting screws74. The centering guides 71 are preferably off a yielding character orcomposed 'ofi'flat springs so that the outer ends of the springsm-ayyieldand permitan abnormally long can body .to pass without binding orsticking. The side guides 70 are cut away, as will be readily understoodfrom Fig. 3, toadmit the Hanging rollers into the ends of the canbodies.
